I have a HD Brawler seat for '04-'08 Sportsters with the larger tank, model # 52940-04A. I found out the hard way that there is another model # (52941-04A) that correctly fits the Nightster. Although this seat mounts on the Nightster it doesn't reach the tank and angles up at the front, so itjust doesn;t look right. Like brand new. $210 shipped. I bought a Corbin Hollywood Solo instead because my dealer told me the correct seat # for the Nightster was on "permanent" back order.
